Pressure Control Type MP

Type MP is a Single Pole double throw (SPDT) pressure control for stopping and starting small refrigeration compressors using CFC, HCFC, HFC, and R717 refrigerants. These switches are available in Low pressure, High pressure and Combined High/Low pressure versions.

The construction is simple and sturdy. The device is enclosed in a dust proofed mild steel casing and all parts are rust proofed for long life. Starting and stopping pressures can be set independently and the device has clearly read setting scale for reference.

Pressure Switch Type PS/PSU

Indfos pressure switch type PS/PSU is a triple pole device, meant to regulate pressure in small air compressors and water pressurization plants.

These switches cut off a 3-phase power supply when the pressure rises to a preset value and cuts in the power supply when the pressure falls to another predetermined value. Both cut off and cut in pressures are independently adjustable. All models are provided with a manual cut off switch (except PSU15X). Type PSU switch is additionally provided with a relief valve, which ensures load free starting of the compressor.

Pressure Switch Type IPS

Industrial pressure switch IPS, is an electromechanical device that senses changes in pressure and provides electrical contact closure at predetermined values. IPS pressure switch may be used to energize an alarm or may directly control the process by cycling pumps, shifting valves etc.

IPS is the most economic device in our wide range of pressure switches. The construction is simple, yet sturdy. The mechanism is enclosed in a dust proof mild steel casing and all parts are rust proofed for long life. Range and Differential values can be set independently and the device has clearly read out setting scale.

Pressure Switch Type RT

Indfos RT Series Pressure switch is produced using technology provided by Danfoss Denmark. These Switches are sturdy, robust and reliable devices meant for Industrial applications. Over one million units have been used in a variety of applications.

RT Series pressure switches utilize a seamless bellows as sensing element. The bellows can be either phosphor bronze or stainless steel to suit various kinds of process medium. The mechanism is enclosed in a weather proof (IP66) enclosure which can be of either DMC or Die Cast Aluminium. Various kinds of switching elements can be provided to meet required electrical load specifications. Both Range and Differential can be independently adjusted. All models feature ± 1% repeatability and device has clearly read setting scale.

Pressure Switch Type B

Indfos B series Pressure Switches are produced using technology provided by Dresser Industries USA, (ASHCROFT Division). These are sturdy, robust and precise devices, for use in process industries.

Available in various ranges covering pressure from 2.5 mm H2O to 210 Kg/cm2. B-Series switches utilise a diaphragm sealed piston sensor. This rugged sensor provides set point repeatability of ± 0.5%. Diaphragms are available in Buna-N, Viton, Teflon, Kapton, Stainless steel & Monel construction making the switch suitable for virtually any process fluid. Enclosures are available in weather proof (IP 66) and explosion proof (II A, B & C) versions and are die cast aluminium as a standard. A wide variety of 1 SPDT or 2 SPDT micro switches including hermetically sealed micro switches are available to meet different requirements of electrical ratings and environmental conditions.
